Bulma VS Nice Launch
Goku was stronger going by their respective performances against Pure Buu, but not strong enough to stomp him or anything. Call me crazy, but I think Mr. Buu could actually just outlast him, and eventually kill him.
I view Hildegarn as the movie version of Buutenks, so they should be about even in strength. Buu takes it due to superior intelligence and abilities.
If he can two-shot Gohan, then none of the others can make any difference.
Tao Paipai solos effortlessly. He beat up post-21st Goku without even using his full power, being completely unharmed by the Kamehameha. These guys just can't hurt him.
Chi Chi goes through them all like a hot knife through butter. A power level that would be relevant at the 22nd Budokai will do that...
Hmmm... I see Cyborg Tao as being 150-160 or so. Against the 139 Roshi and 120 Crane Hermit... it'd be a good fight. But, their teamwork, experience, and the fact that they're not MUCH weaker than him will let them take it IMO. Roshi would have a decent chance himself. Giving him Crane Hermit as back-up is the lock on the door so to speak.
Nail kills them all.
I'm assuming this is Daimao arc Yajirobe? I don't know about those characters, so I can't comment.
Uh... Kami loses. Badly. Cultivars = 1,200. Kami = <408.
I'm assuming this is filler arc Garlic Jr. He and Freeza would be on par in terms of power, maybe with Freeza slightly in the lead. Freeza is a better fighter than Garlic Jr, but his immortality means Freeza has no real way to put him down. He could just break all his limbs and leave him there, of course, but I see Garlic Jr being able to outlast Freeza before that happens.
So Videl vs a tall muscular man. I think she's got this.
No way to tell.
If they get a bit of prep time to plan their assault, I think the team can manage something. They'd need to keep the pressure on Nappa, though, and not lose morale when some of them start dying. Or they could just all hold down Nappa while Piccolo spends a minute or so charging a weak (but still sufficient) SBC.
Vegeta. Cui has no fighting skill at all and a defeatist attitude, so despite being equal in power to Vegeta, he'll lose badly.
Goku. Even if they both fail at drawing out the powers of their bodies (which seems unlikely; Goku mocked Ginyu for his inability to make his mind and body one), Ginyu's body is stronger than Goku's body (without Kaio-ken). So if they both drop to about one quarter of their respective powers, Goku in Ginyu's body would still be able to beat the hell out of Ginyu in Goku's body.
Somehow, Lunch can run nearly as fast as Usain Bolt, and hit as hard as a heavyweight boxer. Nice Lunch is still the same person, and so should be capable of the same feats. Bulma loses.
